Yakadzama kuchengetedza kweiyo hydraulic cylinger yekongiri pombi pombi yerori boom 

Concrete pombori yembamba inodonhedza zvakanyanya pane hydraulic cydraulic cydrinders kuti ubate chaiyo uye yakagadzikana kusimudza, kuwedzera, uye kupeta mafambiro. Iyi cylinda inoshanda pasi pekumanikidzwa kwakanyanya, mitoro inorema, uye mamiriro ekushanda ane hutsinye (ivhu, guruva rekuchengetedza), nekugadzirisa nguva nenguva kuti vadzivise kukundikana kamwe kamwe uye kuve nechokwadi chekuchengetedza. Chinyorwa ichi chinonyatsoenderana nematanho akakosha uye ehunyanzvi ekugadzirisa hydrauc cydraulic pombi yemapombi, discence yekugadzirisa, kuongororwa, kuongororwa, kuongorora, kuongororwa, uye kuongororwa kwekugadzirisa.

1. Pre-Kugadziriswa Kugadzirira: Kuchengetedza uye Chishandiso Kugadzirira

Kuchengetedzeka ndiko kukoshesa kwekutanga usati watanga chero basa rekugadzirisa. Kutanga, park the concrete pombi rori paburi, rakasimba pasi uye kuita brake yekupaka. Deredza boom kune yakasarudzika nzvimbo yakatarisana Dzima injini yerori uye kudzima bhatiri kuti udzivise tsaona activation yeiyo hydraulic system. Tevere, sunungura kudzvanywa kwakawanda muHydraulic Coliticums

Kuti ugadziriswe mudziyo, unganidza zvishandiso zvakasarudzika kuti urege kukuvadza zvidimbu. Zvishandiso zvinodiwa zvinosanganisira: Seti yeTorque Wrenches (ine huwandu hwe0-500 NDELLING DZVANYENGETSE), yekushambadzira piston mavharuvhu), sosi yekunyora yemukati (kuti utarise madziro emukati yegomba oiri corrosion).

2. Disasing of the hydraulic silinda: nhanho-ne-nhanho uye kukuvara kudzivirira

Disasset the cylinder mune yakachena, guruva-emahara musangano (kana shandisa guruva rekuvhara kana dzinoshanda kunze) kudzivirira zvinosvibisa kubva kuHydrauic system. Iyo yekubvisa kutevedzana inofanirwa kutevera iyo cylinder's Chimiro dhizaini kuti udzivise deformation

1. Bvisa kubatana kwekunze. Maka pombi imwe neimwe uye yakabatanidzwa nechero (i.e., "inlet piipe - tsvimbo inopera") kuti udzivise zvisirizvo panguva yekudzokorora. Plug iyo pombi ye pombi uye silinda mafuta maburi nemapurasitiki akachena emapurasitiki ekudzivirira guruva kana marara kubva mukupinda.
2. Dismantle yekupedzisira cap uye piston tsvimbo: Gadzirisa iyo cylinder barrel pane disasembly kumira. Shandisa torque wrench kusunungura mabhawa ekupedzisira ekupedzisira cap (tsvimbo inopera) kuCylinder Barrel-Nyorera Torque Zvakare (Sevha, 80-120 NBOLTS) Kuti udzivise iyo yekupedzisira cap kubva kuCOMTING Mushure mekubvisa mabhodhi, shandisa rubber mallet kuti utore magumo cap zvinyoronyoro uye ubudise kunze kwakatwasuka. Zvadaro, zvishoma nezvishoma dhonza tsvimbo
3. Disassemble zvemukati zvikamu. Tora chisimbiso chechisimbiso (kusanganisira chikuru chisimbiso, uye backup mhete, uye buffer chisimbiso) kubva piston uye kupera cap-shandisa purasitiki kuti urege kukuvadza chisimbiso chegungwa.

3. Chikamu chekuongorora: Key maitiro ekutsiva

Chikamu chimwe nechimwe chakasanganiswa chinofanira kuongororwa zvakanyanyisa kuona kuti kugadzirisa kana kuitsiva. Izvi zvinotevera zvinhu zvakakomba zvekuongorora uye zviyero:

• Cylinder barrel: Tarisa rusvingo rwemukati rwekukanda, kupararira, kana kupfeka. Shandisa sosi yemukati tester yekuyera kuyerera-kana ichipfuura R0.8 Zvekuita madiki (kudzika <0.2 mm), shandisa sandiper
• Piston tsvimbo. Shandisa dial chiratidzo kuyera zvakananga - kana iyo yakakotama inopfuura 0.5 mm pamamita, iyo tsvimbo inofanira kutaurwa (uchishandisa hydraulic in the mess) kana kutsiviwa. Tarisa iyo chrome ichipfuudza ukobvu nekoreti inokona; Kana iri isingasviki 0.05 mm, bvisa zvakare shamhu kuti udzivise kuora.
• Zvisimbiso uye O-Mhete: Wongorora marara, kuomesa, kana kusvibiswa. Kunyangwe kana pasina kukuvara kuri pachena, kutsiva zvisimbiso zvese nevatsva (kunge zvisimbiso zvinosvibisa nekufamba kwenguva nekuda kwekuchera kwemafuta uye tembiricha shanduko). Ita shuwa zvisimbiso zvitsva zvine ukuru hwacho uye zvinhu zvemukuru, shandisa fluororubber zvisimbiso zveCyliters inoshanda munzvimbo dzakakwirira-tembiricha (pamusoro 80 ° C) kuti udzivise kukwira kakawanda.
• Kutungamira Sleeve uye piston. Ongorora iyo Piston's Kuiswa Solaling Grooves yekushongedza; Kana iyo yakadzika yakadzika yakaderedzwa neinopfuura 0,1 mm, kutsiva iyo piston kuti ive nechokwadi chekuti chisimbiso chinokodzera zvakasimba.

4. Reasembly: chaiyo yekushandisa kuve nechokwadi chekuisa chisimbiso

Kugadziriswazve ndiko kudzoreredza kwekubvisa disasing, asi kunyatsojeka kunokosha kuti udzivise kubhururuka kana kukundikana kushanda. Tevedza aya makuru matanho:

1. Zvakachena zvikamu: Pamberi pekuchenesa Pukuta zvikamu zvine mhepo yakamanikidzwa (kudzvanywa <0,4 mpa) kudzivirira mvura kana kusara kubva pakuramba.
2. Isa Zvisikwa. Kuti uve Chisimbiso chikuru (i.e., u-mukombe wekusimbisa), ita kuti muromo wacho unotarisana neyekufambisa kwemafuta-kusarongeka kwekusimbisa kwakanyanya. Shandisa chishandiso chekuisa chisimbiso (sleeve yepurasitiki) kusundira chisimbiso muGroove, kudzivisa kusimbisa.
3. Unganidza piston uye piston tsvimbo. Shandisa torque wrench kuve nechokwadi kunyange kumanikidza, uye kukiya iyo nati ine cotter pin (kana yakashongedzwa) kudzivirira kusunungura panguva yekushanda.
4. Isa piston tsvimbo mu cylinder barrel. Pusha tsvimbo ye piston mubhari zvishoma nezvishoma uye yakatwasuka, ichisimbisa iyo piston isingaderedze nemadziro emukati memukati. Zvadaro, gadza kumberi kwekupedzisira cap, isa bolt mabhegi mune crisscross maitiro (torque inofanira kuenderana nekutaura kwemugadziri-i.g., 100 N m um for m18
5. Unganidza mafuta mapaipi: Tambanudza mafuta eafuta uye zvekunze mapepa maererano nemarambi akaitwa panguva yekubvisa. Simbisa iyo pombi majoini ne torque wrench (i.e., 40-60 N · ye 1-inch pipes) kuti udzivise-kusimbisa, iyo inogona kukanganisa tambo.

5. Kutumira-Kugadzirisa Kuongororwa: Veresa performance uye kuchengeteka

Mushure mekudzokorora, kuitisa miedzo yakazara kuti ive nechokwadi chekuti hydraulic cylinder inoshanda kazhinji:

• Hapana-mutoro bvunzo: Batanidza bhatiri uye utange iyo injini yerori. Ita kuti ubate boom control lever kuti uwedzere uye kudzoreredza cylinder 5-10 nguva pakumhanya kwakadzika (10-15 mm / s). Cherekedza kuti ubve pamapepa emapepa emapepa uye mafuta emafuta majoini-kana kuti leaky zvichiitika, imbomira muedzo nekukurumidza uye tarisa chisimbiso chekuisa kana bolt torque.
• Mutoro bvunzo: Shandisa kumanikidza Gauge kuyera iyo hydraulic system inomanikidza panguva yekushanda. Wedzera boom kune iyo yakareba urefu uye shandisa mutoro (50% yeiyo yakaderedzwa mutoro, .g. Tarisa kana iyo cylinder inobata iyo mutoro wakanganisa
• Operation bvunzo: Bvunza kumhanya kwecylinder uye kupindura nekugadzirisa iyo boom inosimudza uye kuwedzera kumhanya Ita shuwa kuti kufamba kwakatsiga

6. Mazano ekugadzirisa uye post-kugadziridza kuchengetedza

Kuti uwedzere hupenyu hwebasa hweiyo yakagadziriswa silinda cydruber, tevera mazano aya:

• Kugara uchichinja mafuta. Shandisa mafuta anosangana nezvinodiwa zve system (i.ef.
• Geza mweya wedenga: Iyo hydraulic system yemhepo inodzivirira guruva kubva mukupinda-kuchenesa maawa mazana mashanu ekushandisa uye kuzvitsiva maawa ese e1000.
• Kuongorora Kwezuva Nezuva. Kana ruzha rwehurume kana kufamba zvishoma nezvishoma kunoonekwa, kurega kushanda uye kuongorora cylinder pakarepo.

Mhedziso

Iyo hydraulic cylinder chikamu chepakati chekongiri yemapombi yemapombi, uye hunhu hwayo hunobata zvakananga zvinokanganisa kugona kwemarori uye kuchengeteka. Nekutevera matanho akazara ekugadzirira-kugadzirira, akagadziridzwa Kugara uchichengetera nguva nenguva yekutsiva kwehono hazvingo kuderedza njodzi kamwe kamwe asi zvakare hupenyu hwebasa rezvese boom system, dzinoverengera pombi yekongiri inoita mumabasa ekuvaka.
